I'm trying to develop a replacement for a BLDC motor driver board and since my first attempt resulted in a few burned components now I'm trying to use the same components they used on the original board but I need help identifying a diode.
The board uses 3 FAN7382 as FET drivers and the schematic on the datasheet shows a diode connected in series with a resistor, labeled DBOOT and RBOOT respectively, but there is no reference to it in the datasheet.
Since I'm not experienced with BLDC motor control I have no idea of the required characteristics for this diode neither I can identify it by the marking (S1) on it.
Even the package is unusual, I'm unable to identify it. The approximate size of the diode is 2.50mm x 1.25mm and the forward voltage is 0.6 Volts.
You can see the diode in picture bellow.
I was able to figure out the reference of the diode. It is a Bourns SD1005-S0180, it has a reverse voltage of 80V, a forward current of 100mA and 4 ns reverse recovery time.
Link to datasheet here.
